Scenario: We want to disable “Sample No” parameter if “Type” parameter value is “Receipt“, otherwise disable “Receipt No” parameter if “Type” parameter value is “Sample” and the parameter must be mandatory if enable.

We have to define concurrent program with the following parameters:

Type (value are Sample or Receipt, using value set independent (ex: “EY_TYPE”))

Run_Mode_S (use SQL Statement with value “select ‘S’ from dual where :$FLEX$.EY_TYPE:null in (‘Sample’)“, and the parameter is not display)

Run_Mode_R (use SQL Statement with value “select ‘R’ from dual where :$FLEX$.EY_TYPE:null in (‘Receipt’)“, and the parameter is not display)
